The 2020 Subaru Impreza uses a standard spin-on oil filter designed for the 2.0-liter FB20 engine. The recommended replacement is the Subaru Genuine Oil Filter, and reputable aftermarket filters that cross-reference to Subaru’s part will also fit as long as they match the FB20 specifications. Verify the exact part number with Subaru Parts using your VIN to be certain.
Oil filter specification
In practice, you should use a Subaru OEM oil filter for the 2.0L FB20 engine. If you choose an aftermarket option, ensure it is a proven cross-reference that matches the FB20’s threading, gasket size, and filtration rating.
To help readers understand options, here are common categories you can consider:
- Subaru Genuine Oil Filter (OEM) for the 2.0L FB20 engine
- Aftermarket cross-reference from well-known brands that match Subaru’s FB20 filter specifications (e.g., Wix, Bosch, Purolator)
- Any filter explicitly listed as compatible with the FB20 engine in reputable catalogs
- Filters purchased from authorized retailers to avoid counterfeit parts
By sticking to OEM or verified cross-references, you ensure proper fit, filtration, and oil flow for the engine’s longevity.
How to verify you’re buying the right filter
Use a methodical approach to confirm compatibility before purchase:
- Consult the owner's manual or the official service manual’s Parts Diagram for the exact filter part number
- Check the number printed on your current filter and compare it to the replacement part’s labeling
- Provide your car’s year, model, and engine (2.0L FB20) when ordering from a parts counter or online catalog
- Use your vehicle identification number (VIN) to fetch the precise filter specification from Subaru Parts or a trusted aftermarket catalog
If you’re unsure, ask a dealer or a qualified mechanic to confirm the correct part number for your specific vehicle configuration.
Summary
The 2020 Subaru Impreza relies on a standard spin-on oil filter designed for the 2.0-liter FB20 engine. The safest route is to use the Subaru Genuine Oil Filter, with reputable aftermarket cross-references available. Always verify the exact part number using your VIN or through Subaru Parts to ensure a precise match, and opt for trusted brands if you go aftermarket.
